Make ReflectorImpl use mailboxes

- fixes ui::Layer::SetTextureMailbox to not be hard-coded for software
  frames.
- adds a ui::Layer::SetTextureSize to update the size without sending a
  new mailbox (since it doesn't change).
- entirely removes ui::Layer::SetExternalTexture and ui::Texture, and
  derived classes.
- significantly changes the ReflectorImpl implementation:
  * an OwnedMailbox is created on the main thread, using the shared main
    thread context.
  * the mailbox is passed to the impl thread, that creates a texture out
    of it with the OutputSurface context, and does operations on that.
  * the mailbox is passed to the layer.
  * if the OutputSurface is recreated (assuming, after a lost context),
    the OwnedMailbox is recreated, and passed to the impl side again,
    together with the new surface.
  * the OwnedMailbox takes care of deleting the texture, whether because
    of a lost context, or when the ReflectorImpl is shut down.
